LANTERN-B URNER.

To all whom it may concern:

Be it known that 1, WILLIAM S. HAMM, a citizen of the United States, and resident of Lakeside, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lantern-Burners, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to lantern burners which comprise a wick-tube and a wick raiser in the form of a star wheel carried by the shaft.

The object of the invention is to render the Wick raiser more certain in its action, particularly for the purpose of preventing the descent of the wick due to jarring or vio lent motion of the lantern; and it consists in means for frictionally holding the star wheel or its shaft against rotation, and, more specifically, in a spring yieldingly forcing the shaft against its bearing.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of the burner, the wick being shown in detail; Figs. 2 and 3 are sectional views, respectively, on the lines 2-2 and 33 of Fig. 1, the wick being omitted.

The burner is provided with a chambered body 10, preferably of sheet metal and having a threaded shank 11 for engagement with the neck of the lantern font, not shown. The wick tube 12 projects vertically through the center of the body, extending downwardly a suitable distance to serve as a guide for the wick and upwardly a suitable distance to properly locate the flame, and is shown in this instance as round, though it may take any desired form.

A friction wheel 13, preferably in star form, is located within the body 10 and projects through an aperture in the tube 12 to engage the wick for the purpose of raising it. This Wheel is carried by a shaft 14 passing through the body 10 and provided at one end with a grip 1 5 by which it may be easily turned.

The apertures in the body 10 within which the shaft 14 is located, are of greater diameter than the shaft, and a bearing plate 16 for the shaft is fixed within the body, the shaft being held yieldingly against it by means of a spring 17, shown as being bowed in form.

Serial No. 366,999.

The ends of the spring are shaped to conform to the surface of the shaft, as shown at 18, 19, in order to constitute prolonged bearings therefor, and its crown bears against the wall of the body 10, as shown at 20. The spring is contractile in character, its elasticity tending to urge its ends toward each other and consequently apply the desired pressure to the shaft to hold it yieldingly to the bearing plate 16.

While I have shown and described a wicktube extending entirely through the body of the burner and a friction device for raising the wick, taking the form of a star wheel, it will be understood that the invention is applicable to any form of burner in which there is a wick passage and a friction device operated by a rotatable shaft for raising and lowering the wick.

I claim as my invention 1. In a lantern burner, in combination, a chambered bodyhaving a wick passage therethrough, a star wheel projecting into the passage, a shaft for carrying the wheel, a plate secured to the side walls of the body extend ing across its chamber and serving as a bearing for the shaft, and a spring yieldingly holding the shaft against the plate.

2. In a lantern burner, in combination, a chambered bodyhaving awick passage therethrough, a star wheel projecting into the passage, a shaft carrying the wheel, a plate secured to the side wall of the body and extending across its chamber and serving as a bearing for the shaft, and a bowed spring re acting between the wall of the body and the shaft to hold the latter against the plate.

3. In a lantern burner, in combination, a chambered bodyhaving awick passage there through, a star wheel projecting into the passage, a shaft for carrying the wheel, a plate secured to the side walls of the body extending across its chamber and serving as a hearing for the shaft, a bowed spring reacting between the wall of the body and the shaft to hold the latter against the plate and having its ends conforming to the shape of the shaft to form prolonged bearings therefor.
